The problem lies in when I already have the image files, and I also may or may not have all exif data.
To clear up: I'm only interested in a technique within Gimp (if exist / is possible) to solve this problem. But, yes, I do use manual settings on camera when applicable, the question relates to the instances where this wasn't done for some unrelated reason.
